A multi-scale analysis of magnetic forces between rigid bodies

I will present recent results about magnetic force formulae for two rigid magnetic bodies. Using different scales to describe the distance between the bodies, we discuss continuum limits of atomistic dipole-dipole interactions. This allows to link a classical force formula and a limiting force formula obtained earlier as a discrete-to-continuum limit for bodies being in contact on the atomistic scale. This is joint work with Bernd Schmidt, cf. MPI MIS Preprint 29/2007.
